Monitor Setup
Refer to Figure 18
The standard DICKEY-john
® PM400 system monitors
the following elements of a YP625TD and YP925TD
planter:
• Seeds at each row unit seed tube.
• Ground speed.
See “Seed Monitor Console Installation” on page 116.
Refer to the DICKEY-john ® DICKEY-john ®
PM300-332-400 Planter Monitor Operator’s Manual
(11001-1372) for monitor operations.
After installation, and prior to first field use, the monitor
must be setup with the row spacing and speed sensor
constant, as well as your preferences for information
display. Row count is auto-assigned, but any other
DICKEY-john
® defaults are not likely to be correct for
your planter.
Row spacing data may be found in the Appendix.
For speed setup, Great Plains recommends using the
122m (400-foot) calibration described in the
DICKEY-john
® manual, rather than using the theoretical
“# of pulses” from Appendix B. Perform the calibration
run in representative field conditions, as soil conditions,
surface looseness and other tillage practices can cause
variations in the effective rolling radius of the ground
drive wheel.
Prior to each planting session, set any desired limits for
speed and population for the current crop.
Marker Setup (Option)
Prior to first use, check and adjust:
• “Marker Speed Adjustment” on page 120.
Prior to first use, and whenever changing row spacings,
set or reset:
• “Marker Extension” on page 120.
Prior to each planting session, check and adjust:
• “Marker Disk Adjustment” on page 48.
